Vibration Characteristics of Rolling Tires

Tires are the only load transfer mechanism between a vehicle’s suspension and the road. Consequently, tire vibration has a significant impact on ride quality and vehicle interior noise.
To accurately predict the frequencies and mode shapes of a rolling tire, Abaqus allows pre-loading and gyroscopic effects to be included in a complex frequency extraction. These effects can also be included in a forced response analysis of the rolling tire to predict the  spindle forces contributing to vehicle noise and vibration. In this Technology Brief, we outline the analysis methodology for determining the vibration characteristics of stationary and steadily rolling tires.
